Do you need the correct springs for the device to work. The extra foam earplugs may help a little bit but don’t have the same affect as a spring
Quiz about adding dense mass to a vibration isolation application!
There are two steps in this quiz:
1) Hypothetically, you have a DAC that is very solidly built on all sides and weighs 25 lbs.
This DAC currently has three Nobsound vibration isolation devices under it, the springs of which are about 50% compacted and are damped by foam ear plugs inserted inside of them. The vibration isolation effect with this setup is merely middling according to a cell phone seismograph app.
2) You add a 25 lb granite slab to the top of the DAC with a 1/8-inch rubber mat between it and the DAC, and then add the appropriate number of ear plug foam damped springs to each Nobsound device in order to get all Nobsound device springs back to about 50% compacted.
The question: What do you think is the sonic result of step 2?
